产品特点 FEATURES

1 Front-end unit: MEAN WELL NMP1K2 (1200W maximum power, 6 modular slots) with wide input range (90-264VAC/120-370VDC), frequency range of47-63Hz, high power factor (>0.95@230VAC full load) and efficiency (up to91% with H/K modules at24V/48V full load)

2 Modular design: Supports NMS-240 series single-output modules (5V/36A,12V/20A,24V/10A,48V/5A options, each up to240W) with adjustable output voltage (e.g.,5V:3-6V,12V:6-15V,24V:15-30V,48V:30-55V), low ripple&noise (max100mVp-p for5V,250mVp-p for48V), and tight regulation (line/load regulation as low as ±0.2% for48V modules)

3 Functional features: Remote sense (compensates voltage drop up to0.5V), remote on/off control (local/global), DC OK signal (TTL level indicating output status), current sharing (for parallel operation of modules), output voltage/current programming (via PV/PC pins), and auxiliary power outputs (5V/2A for front-end,5V/10mA for modules)

4 Safety&protection: Complies with ITE and medical safety standards (2x MOPP isolation between primary and secondary), with multiple protections: overload (constant current limiting or hiccup mode), overvoltage (shutdown, re-power to recover), overtemperature (shutdown, auto-recover when cool)

5 Mechanical: Compact size (NMP1K2:250×127×41mm, NMS-240 module:118.5×37.9×18mm), suitable for rack mounting with specified torque (M4 screws:7-10 Kgf-cm)

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, DCS systems, servo drives, and sensor networks requiring multiple stable voltage outputs

2 Medical equipment: Suitable for devices compliant with medical safety standards (2x MOPP isolation) like diagnostic instruments, patient monitors, and lab equipment

3 Test&measurement: Supporting multi-channel test setups needing precise voltage/current control and stable power

4 Communication systems: Powering servers, routers, switches, and telecom equipment with high reliability and current sharing capability

5 LED&lighting: Driving LED arrays or control systems needing adjustable voltage and low ripple

6 High-power applications: Parallel operation of modules for redundant or high-current requirements (up to6 modules for NMP1K2, total1200W)

注意事项 PRECAUTIONS

1 Mounting: Use recommended screw sizes (M4 for front-end, M3.5 for modules) and torque (7-10 Kgf-cm for front-end), avoid exceeding max penetration depth (4mm for front-end)

2 Derating: For output voltage <12V and ambient temp between-15°C and-30°C, derate output current to90% of rated value; refer to derating curves for other conditions

3 ON/OFF control: Install the shorting connector (RC1 to GND-P) if global ON/OFF is not used; local control for modules uses RC2/RC3 pins (open=ON, short=OFF), global control uses RC1 pin (short=ON, open=OFF)

4 Parallel operation: Connect CS pins together, ensure output voltage difference <0.2V between modules, total power ≤1200W for NMP1K2; use short/large diameter wires; PC function is disabled in parallel

5 Protection handling: Re-power the unit to recover from overvoltage/overload shutdown; overtemperature shutdown auto-recovers when cool

6 Wiring: Use twisted pairs for remote sense lines to minimize noise; follow wire gauge recommendations (20-26AWG for module outputs)
